Furukawa Electric Co. Ltd has announced the development of the S121A optical fiber fusion splicer suitable for use in LAN and FTTH services that require simple and low cost connection installations.

Fusion splicing offers reliability as well as high resistance to environmental factors, enabling the method to be widely used in optical fiber connections. However, the method has not been suitable for use in FTTH services due to the large size and high cost of the equipment. The company claims that the S121A answers these concerns.

The S121A measures and weighs about 1/3 that of the company's previous S199M4 fusion splicer. The S121A weighs 980g alone and 1.15kg with a removable battery. It features a T-shaped body to enable connections using a minimum excess fiber length when the fiber head is inserted into the enclosure, and at the same time allows the user to hold the fusion splicer in one hand.

The device handles single-core optical fibers and is claimed by the company to perform automatic connections in 13s. The fiber is set in the holder, and the unit executes all operations from pre-processing to connection. An enlarged image of the fiber is displayed using a CCD camera and a 2.5-inch color LCD monitor, to ensure stable and high-quality connections.

The optic fiber connection type can be switched between single-mode and multimode by selecting a pre-set connection program. Furukawa also claims that connection loss in terminal connections is typically <0.1dB in single-mode fiber connections.

The splicer draws power from a removable, rechargeable battery or an optional dc adaptor to allow ac power input. An optional sleeve heater or reinforcement tool is also offered allowing connections to be strengthened using Japanese thermal protection sleeves or the ULTRAsleeve used in the U.S.
